Description

Technical Field

[0001] This utility model belongs to the field of plant fiber tableware processing technology, and specifically relates to a hydrophobic coating spraying device for plant fiber tableware. Background Technology

[0002] Plant fiber tableware is made from agricultural waste through high-temperature and high-pressure molding. It has advantages such as being biodegradable, low-carbon, environmentally friendly, safe and non-toxic. It is suitable for takeout, home and medical fields and has a broad market prospect. It is an important solution to replace disposable plastics and can be used in conjunction with industrial composting to achieve the best degradation effect.

[0003] Because plant fibers have a porous structure, they are prone to leakage or softening when in direct contact with liquids. Spraying a hydrophobic coating onto their surface fills the gaps between the fibers, forming a physical barrier that prevents the tableware from absorbing water, deforming, or cracking. It also prevents plant fiber tableware from easily becoming moldy and breeding bacteria in humid environments. This hydrophobic coating further blocks moisture, enhancing the structural stability and antimicrobial capabilities of the tableware.

[0004] In existing technologies, hydrophobic coatings are generally applied to the surface of plant fiber tableware using a spray gun. Since the plant fiber tableware itself is lightweight and the hydrophobic coating sprayed from the spray gun has a certain impact force, it is necessary to position the tableware during the spraying process to avoid shaking that could affect the coating quality. However, when replacing the plant fiber tableware, the coated tableware needs to be disassembled and the uncoated tableware needs to be fixed in place, resulting in a long downtime and reducing the efficiency of the tableware spraying process. Utility Model Content

[0005] To address the problem that replacing plant fiber tableware requires disassembling the coated tableware and fixing the uncoated tableware, resulting in long downtime and reduced coating efficiency, this invention proposes a hydrophobic coating spraying device for plant fiber tableware to overcome the aforementioned technical problems in existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a hydrophobic coating spraying device for plant fiber tableware, including a spraying machine: The spraying machine is equipped with a drive assembly, a rotating assembly, a transmission assembly, and a clamping assembly. The drive component has its output end fixedly installed at the bottom end of the rotating component, so that the drive component drives the rotating component to rotate. The transmission component has its outer surface slidingly disposed with the interior of the rotating component, so that the rotating component drives the transmission component to operate when it rotates; The clamping component is fixedly installed at its bottom end to the top end of the transmission component, so that when the transmission component is running, it drives the clamping component to clamp or release the tableware.

[0007] Furthermore, the drive assembly includes a mounting bracket, the top of which is fixedly mounted inside the sprayer, and a motor is fixedly mounted at the bottom of the mounting bracket.

[0008] Furthermore, the rotating assembly includes a rotating shaft, the outer surface of which is rotatably connected to the interior of the spraying machine, the bottom end of which is fixedly installed to the output end of the motor, and a rotating plate is fixedly installed at the top end of the rotating shaft.

[0009] Furthermore, the transmission assembly includes a sliding shaft, the outer surface of which is slidably disposed with the interior of the rotating plate, a mounting plate fixedly connected to the top end of the sliding shaft, a fixing plate fixedly connected to the bottom end of the sliding shaft, a return spring fixedly connected to the top end of the fixing plate, and the top end of the return spring fixedly connected to the top end of the rotating plate.

[0010] Furthermore, the transmission assembly also includes an arc-shaped base, the bottom end of which is fixedly installed with the top end of the spraying machine, and the top end of the arc-shaped base is in contact with the bottom end of the fixing plate.

[0011] Furthermore, the clamping assembly includes a support base, the bottom end of which is fixedly installed to the top end of the spraying machine, and a clamping rod is rotatably arranged inside the support base, with a clamping block fixedly connected to the top end of the clamping rod.

[0012] Furthermore, the clamping assembly also includes a movable slot, which is formed inside the clamping rod. A movable seat is movably connected inside the movable slot, and the bottom end of the movable seat is fixedly installed to the top end of the mounting plate.

[0013] This utility model has the following beneficial effects: 1. This utility model places the tableware on the top of the clamping component, then activates the drive component, causing the rotating component installed at the output end to rotate. The rotating component then drives the internally sliding transmission component to perform circumferential motion. During the rotation of the transmission component, it moves downward under its own compressive stress, thereby causing the clamping component installed at the top to move. The clamping component clamps the tableware during this movement. As the clamping component continues to move, it carries the clamped tableware into the spraying machine. Since there are two sets of clamping components, when one set of clamping components carries the uncoated tableware into the spraying machine, the other set of clamping components carries the coated tableware out of the spraying machine. This allows the positions of the two sets of clamping components to be interchanged, facilitating the replacement of coated tableware. This avoids the spraying machine stopping when changing tableware and improves the coating efficiency of the hydrophobic coating spraying equipment for plant fiber tableware.

[0014] 2. This utility model uses a sliding shaft to drive the mounting plate downwards. When the mounting plate moves up and down, it can drive the movable seat mounted at the top to move up and down. Since the interior of the movable seat is movably connected to the interior of the movable groove, and the movable groove is opened at one end of the clamping rod, when the movable seat moves up and down, it can cooperate with the movable groove to push one end of the clamping rod to move up and down, so that the middle part of the clamping rod rotates around the support seat as the center, thereby causing the other end of the clamping rod to perform a circular motion around the support seat as the center. This allows the clamping rod to drive the clamping block fixed at the top to clamp or release the tableware, thus facilitating the replacement of tableware.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Please see Figures 1-6 As shown, this utility model is a hydrophobic coating spraying device for plant fiber tableware, including a spraying machine 1: The spraying machine 1 is equipped with a drive assembly 2, a rotating assembly 3, a transmission assembly 4, and a clamping assembly 5. The output end of the drive component 2 is fixedly installed at the bottom end of the rotating component 3 so that the drive component 2 drives the rotating component 3 to rotate. The transmission component 4 has its outer surface slidingly disposed with the interior of the rotating component 3, so that the rotating component 3 drives the transmission component 4 to operate when it rotates; The clamping component 5 is fixedly installed at its bottom end to the top end of the transmission component 4, so that when the transmission component 4 is running, it drives the clamping component 5 to clamp or release the tableware.

[0022] In use, the tableware is placed on the top of the clamping component 5, and then the drive component 2 is activated, causing the rotating component 3 installed at the output end to rotate. The rotating component 3 drives the internally sliding transmission component 4 to perform circular motion. During the rotation of the transmission component 4, it moves downward under its own compressive stress, thereby causing the transmission component 4 to move the clamping component 5 installed at the top. The clamping component 5 clamps the tableware during the movement. As the clamping component 5 continues to move, it carries the clamped tableware into the interior of the spraying machine 1, where the spraying machine 1 sprays the tableware. At the same time, the clamping component 5 inside the spraying machine 1 moves out, thus carrying the sprayed tableware out of the interior of the spraying machine 1. When it reaches a fixed position, the transmission component 4 drives the clamping component 5 to move upward, thereby releasing the clamping and fixing of the tableware.

[0023] This invention places the tableware on the top of the clamping component 5, then activates the drive component 2, causing the rotating component 3 installed at the output end to rotate. The rotating component 3 then drives the internally sliding transmission component 4 to rotate in a circular motion. During the rotation of the transmission component 4, it moves downward under its own compressive stress, thereby causing the top-mounted clamping component 5 to move. The clamping component 5 clamps the tableware during this movement. As the clamping component 5 continues to move, it carries the clamped tableware into the spraying machine 1. Since there are two sets of clamping components 5, when one set of clamping components 5 carries the uncoated tableware into the spraying machine 1, the other set of clamping components 5 carries the coated tableware out of the spraying machine 1, allowing the two sets of clamping components 5 to switch positions. This facilitates the replacement of coated tableware and avoids the spraying machine 1 from stopping when changing tableware, thus improving the coating efficiency of the plant fiber tableware hydrophobic coating spraying equipment.

[0024] In one embodiment, the drive assembly 2 includes a mounting bracket 201, the top of which is fixedly mounted inside the sprayer 1, and a motor 202 is fixedly mounted at the bottom of the mounting bracket 201.

[0025] The mounting bracket 201 is designed to limit the height of the motor 202 mounted at the bottom and to provide a relatively stable operating state for the motor 202. The motor 202 is a stepper motor, and its speed and stopping position are controlled according to the frequency and number of pulse signals, so as to control the motor 202 to rotate at a fixed angle for intermittent start and stop.

[0026] In one embodiment, the rotating assembly 3 includes a rotating shaft 301, the outer surface of the rotating shaft 301 is rotatably connected to the interior of the spraying machine 1, the bottom end of the rotating shaft 301 is fixedly installed with the output end of the motor 202, and the top end of the rotating shaft 301 is fixedly installed with a rotating plate 302.

[0027] The rotating shaft 301 installed at the output end of the motor 202 is driven to rotate, so that the rotating shaft 301 drives the rotating plate 302 installed at the top to rotate. Since the motor 202 is a stepper motor, it can work with the rotating shaft 301 to drive the rotating plate 302 to rotate intermittently by 180 degrees, thereby changing the position of the two ends of the rotating plate 302.

[0028] In one embodiment, the transmission assembly 4 includes a sliding shaft 401, the outer surface of which is slidably disposed with respect to the interior of the rotating plate 302, a mounting plate 402 fixedly connected to the top end of the sliding shaft 401, a fixing plate 403 fixedly connected to the bottom end of the sliding shaft 401, a return spring 404 fixedly connected to the top end of the fixing plate 403, and the top end of the return spring 404 fixedly connected to the top end of the rotating plate 302. The transmission assembly 4 also includes an arc-shaped base 405, the bottom end of which is fixedly installed with the top end of the sprayer 1, and the top end of the arc-shaped base 405 is in contact with the bottom end of the fixing plate 403.

[0029] When the rotating plate 302 rotates, it drives the internally sliding shaft 401 to rotate in a circular motion. This causes the sliding shaft 401 to drive the fixed plate 403, which is fixed at its bottom, to rotate in a circular motion. Since the bottom of the fixed plate 403 is in contact with the top of the arc-shaped base 405, and the arc-shaped base 405 is semi-circular, when the fixed plate 403 moves in a circular motion along the arc-shaped base 405, it gradually moves upwards. This allows the fixed plate 403 to drive the sliding shaft 401 along the rotating plate 302. The internal mechanism moves upward, compressing the return spring 404 fixed at the top of the fixed plate 403, and causing the sliding shaft 401 to drive the mounting plate 402 fixed at the top to move upward. When the rotating plate 302, in conjunction with the sliding shaft 401, drives the fixed plate 403 to rotate again, the return spring 404 pushes the fixed plate 403 to remain in contact with the top of the arc-shaped base 405 due to the lowering of the arc-shaped base 405 assembly, thereby causing the fixed plate 403, in conjunction with the sliding shaft 401, to drive the mounting plate 402 to move downward.

[0030] In one embodiment, the clamping assembly 5 includes a support base 501, the bottom end of which is fixedly installed with the top end of the spraying machine 1, and a clamping rod 502 is rotatably arranged inside the support base 501, with a clamping block 503 fixedly connected to the top end of the clamping rod 502. The clamping assembly 5 also includes a movable groove 504, which is formed inside the clamping rod 502. A movable seat 505 is movably connected inside the movable groove 504, and the bottom end of the movable seat 505 is fixedly installed to the top end of the mounting plate 402.

[0031] When the mounting plate 402 moves up and down, it can drive the movable seat 505 mounted at the top to move up and down as well. Since the interior of the movable seat 505 is movably connected to the interior of the movable groove 504, and the movable groove 504 is opened at one end of the clamping rod 502, when the movable seat 505 moves up and down, it can cooperate with the movable groove 504 to push one end of the clamping rod 502 to move up and down, so that the middle part of the clamping rod 502 rotates around the support seat 501 as the center, thereby causing the other end of the clamping rod 502 to perform a circular motion around the support seat 501 as the center. This allows the clamping rod 502 to drive the clamping block 503 fixed at the top to clamp or release the tableware, thus facilitating the replacement of tableware.

[0032] Through the above technical solution, 1. By placing the tableware on the top of the clamping component 5, and then starting the drive component 2, the drive component 2 is activated to drive the rotating component 3 installed at the output end to rotate, so that the rotating component 3 drives the internally sliding transmission component 4 to perform circumferential motion, so that the transmission component 4 moves downward under its own compressive stress during rotation, thereby causing the transmission component 4 to drive the clamping component 5 installed at the top to move, so that the clamping component 5 clamps the tableware during the movement. As the clamping component 5 continues to move, it carries the clamped and fixed tableware into the interior of the spraying machine 1. Since there are two sets of clamping components 5, when one set of clamping components 5 carries the uncoated tableware into the interior of the spraying machine 1, the other set of clamping components 5 carries the coated tableware out of the interior of the spraying machine 1, so that the positions of the two sets of clamping components 5 are replaced, thereby facilitating the replacement of the coated tableware, thus avoiding the spraying machine 1 from stopping when changing tableware, and improving the coating efficiency of the hydrophobic coating spraying equipment for the surface of plant fiber tableware. 2. The mounting plate 402 is moved downward by the sliding shaft 401. When the mounting plate 402 moves up and down, it can drive the movable seat 505 mounted at the top to move up and down. Since the interior of the movable seat 505 is movably connected to the interior of the movable groove 504, and the movable groove 504 is opened at one end of the clamping rod 502, when the movable seat 505 moves up and down, it can cooperate with the movable groove 504 to push one end of the clamping rod 502 to move up and down, so that the middle part of the clamping rod 502 rotates around the support seat 501, so that the other end of the clamping rod 502 performs a circular motion around the support seat 501. This allows the clamping rod 502 to drive the clamping block 503 fixed at the top to clamp or release the tableware, thus facilitating the replacement of tableware.
